The Jelly Bean rollout for Galaxy device has been fast and furious as of late, with Samsung making the update available to nearly all of its current and former flagship devices. Today's the day for T-Mobile's version of the Galaxy S II – but the download is only available via Samsung's Kies software.

In order to pull the update, you'll need to be on the latest official firmware from T-Mobile, and must have at least 50% battery. Otherwise, grab the newest version of Kies, plug up, and get to downloading – the 756MB file is going to take some time on slower connections.
